Bring pasta to a boil and cook according to package directions. Drain.

Start the mac and cheese by sauteeing the sliced mushrooms in a large skillet {you may need to use olive oil to prevent mushrooms from sticking}. Add garlic as the mushrooms begin to release their liquids. Cook until liquids are evaporated.

Then, stir in the chicken broth, onion and salt and pepper, to taste.

Next, blend in the sweet potato puree. Simmer for a few minutes.

Combine corn starch and whipping cream together in a mixing cup and stir until blended.

Slowly stir in the cornstarch mixture into the skillet. Heat until thickened; about 5 minutes.

Then, remove from the heat.

Stir in the pasta and Parmesan cheese.

Serve warm.

With each bit my sister and I took, we laughed more and more! We couldn't believe how much like mac and cheese this tasted, and there was hardly any cheese in it. The orange of the sweet potato looks delightfully like cheese -- maybe it even tricked our brains :)

I'm not sure when you changed it, but thanks so much for posting a print-friendly link for your recipes! It seems like I borrow quite a few of your recipes and it is much easier on me now. I have been following you for a long while now and I am glad my copy and paste days are over!

@ OMG -- you can use light whipping cream, or fat-free half and half, if you wish. I used cream because that's what I had on hand, but have since made it again using half and half. It is just as tasty :) I'll have to try it with milk, but I'm guessing that will work too.

Ok, I can never follow directions, but I'm making something close to this tonight (and trying my best to follow your recipe!) and, I have to say...I'm about to eat the sauce straight up, with a spoon. There's not even any cheese in it yet, and it already tastes like mac n' cheese! hahaha (my sweet potatoes were white, so I made a puree from the sweet potatoes, with carrots for sweetness and color. OM NOM NOM.)

I cooked my sweet potatoes with about 1/2C red lentils in chicken broth, then pureed the whole mixture. The puree tastes about the same and has the same color, so it's a great way to sneak in a healthy protein! Delicious!

When cooking, please make sure to follow kitchen hygiene and safety -- cook meat until internal temperature is at safe levels, always check labels for allergens, and use caution in the kitchen -- I love sharing recipes, but I am not liable for damages done as a result of trying these recipes.
